The place was perfect for my purposes. The space was modern, super-clean and tidy. No frills here -- exactly the things I needed and nothing more. The location really is extremely close to the BTS, and that is not always easy to find in Bangkok!
Lek was probably more responsive and communicative than any BnB host I've ever had. She went above and beyond to make sure I was comfortable and sorted out.
One note: the gym consists of a couple cardio machines, no weights, stability balls etc. The pool is quite nice, though.
